It is widely used in the geological general investigation and exploration, road, railway, port, bridge, water conservancy, tunnel and tall building basic exploration, kinds of hole in concrete structure, river, levees, subgrade grouting hole drilling and direct grouting, civil wells and earth central air conditioner, and etc.

1. Diesel engine and electric motor as power.(convenient for places of insufficient of electricity)2. Integrative Drilling Tower:Tower is supported by two high strength oil cylinder, hydraulic controlling the rise and fall of the tower. The operation is extremely convenient, saving time and labor effort,creating maximum benefit for the user.3. Crawler mobile base or trailer mobile baseThe chassis used crawler /trailer type achieve rapid turnarounds, very convenient for movement.4. Long stroke hydraulic supporting leg can be used for transportation, loading and unloading of the drill automatically without the help of the lifting equipment. The hydraulic leg can rapidly make the drill level in the coordination with the universal level instrument.5. electric-start diesel engine,It greatly reduces the labor intensity of operators, especially more efficient in the cold season when the diesel engine start is difficult, showing its great advantage.6. The machine is equipped with a complete set of independent BW - 160 mud pump, with high pump flow rate and pressure, convenient maintenance, convenient to buy spare and accessory parts all around.
